[PIP-264](https://github.com/apache/pulsar/blob/master/pip/pip-264.md) ### Motivation Using OpenTelemetry, exposes the current consumer-level metrics emitted by the broker and described in the [doc](https://pulsar.apache.org/docs/next/reference-metrics/#consumer-metrics). ### Modifications Similar to topic metrics PR https://github.com/apache/pulsar/pull/22467, navigate all the current consumers connected to the broker and expose their respective metrics in OpenTelemetry format. The metric details can be consulted in the doc PR: https://github.com/apache/pulsar-site/pull/896. Prometheus metric `pulsar_consumer_blocked_on_unacked_messages` has been dropped in favor of OpenTelemetry boolean attribute `pulsar.consumer.blocked` on metric `"pulsar.broker.consumer.message.unack.count`, as these values are tightly related. ### Verifying this change - [ ] Make sure that the change passes the CI checks.
